Biofuels threaten to destroy the Gulf of Mexico

The goal was to reduce 500 acres of the so called " dead zone " in the
Gulf of Mexico, the largest hypoxic zone in the world, where the
excessive blooms of algae, stimulated by pollution, leads to oxygen
depletion. However, the ambitious goal of the U.S.A. to stop the
destruction of many natural habitats is far from reality. The alert
came from a team of researchers at Carnegie Mellon University in
Pennsylvania.
